I am planning to go on a 7-day cruise with my daughter Dec 15 (first time cruiser from Canada). I will rely on shuttle services to/from Bush Airport in Houston to port of Galveston. Are there any hotels within walking distance post cruise in Galveston so I don't have to wait for taxi. I heard the port is busy & chaotic. There will be a long line up to wait for the taxi. Which shuttle offers reasonable transportation to/from Houston? Any places I should avoid to go with my teenage daughter in Houston & Galveston?
